Abstract:
Based on the preliminary research, the tenth-grade students lacked ability in mathematical problem solving of sine rule. One of the factors that influenced this problem was the teacher's learning model, which was still mechanistic. The teacher did not relate between learning and environment or local culture. Based on this, this study aims to develop HLT on the topic of a valid ethnomathematical PBL-based sine rule. The development model used is the Plomp model and the Gravemeijer and Cobb model, which consists of the initial investigation stage, product development stage, and assessment stage. In this article, the discussion is focused on the HLT development stage. The data analysis technique used is descriptive statistics and descriptive techniques. Data collection instruments used: validation sheets, observation sheets, interview sheets, questionnaires, and field notes. This study resulted in the HLT of the sine rule based on PBL nuances of Minangkabau Culture, which met the validity criteria of 0.771 and the characteristics of validity in terms of content and constructs.

Abstract:
The Indonesian government makes efforts to improve students' higher-order thinking skills by implementing a Minimum Competency Assessment or Assessment Kompetensi Minimum (AKM) as a substitute for the National Examination. With the implementation of the AKM, it is necessary to find out how students can solve these questions. This research analyzed students' higher-order thinking skills in solving AKM-type math problems. The research method used is descriptive qualitative research consisting of 3 stages: the preparation stage, the implementation stage, and the data analysis stage. The research was conducted in the odd semester of the 2020/2021 academic year with the research subjects of eleven 8th grade students of SMP IT Raudhatul Ulum Sakatiga, South Sumatra, and SMPN 11 Banjarbaru, South Kalimantan. Data collection techniques used are tests, documentation, observation, and interviews. The data were analyzed qualitatively. The results showed that students with high abilities could solve several questions that required analytical power but were still weak in solving questions that required evaluation. Other students still need to improve their analytical and evaluation skills.

Abstract:
This study aims to understand better student errors in solving mathematics word problems. A Word problem is a problem that has a story or arrangement based on sentences. The qualitative research approach was used. The data were collected by giving tests and interviewing two male high achievers senior high school students in mathematics. The student error analysis adopted the Newman error analysis system. The source triangulation was used to ensure the data validity. Based on the collecting data and data analysis, the decoding/reading error happened caused by students' common understanding or unfamiliarity of the mathematical terms used in the problem. The subjects showed inconsistency in interpreting problem sentences and misused mathematical symbols. Furthermore, the subject encountered difficulties with the arithmetic process, especially fractions and their operation. This research identified students' difficulties in solving problem mathematics word problems. Moreover, this research provides evidence that encourages further research on mathematical literacy, mathematical communication skills, students' arithmetic skills, and the evaluation process of the problem-solving activity.

Abstract:
Many methods and strategies of learning were being searched, made, and invented by a lecturer to provide an effective online learning process. Two years passed, and now Indonesia is on the road to endemic of covid-19 status, which soon caused the permission for offline learning. Indeed, students have their own expectations for this condition. Do they like it? Do they have difficulties so far? Do they want other methods? or other expectations of students which have not been explored yet? Therefore, this research will explore students' expectations of welcoming offline learning using a qualitative research method. The questionnaire was used as the instrument to collect the data from the students in the first year of the pandemic. The instrument mostly asked about the students' opinion of their online learning, then related to their expectations when it became offline learning soon. It was simply analyzed using excel to show the percentage of each data. The result showed that 75% did not like online learning since it impacts their score, which decreased from an average of about 70 to 50. Therefore, many students expect to understand the material with offline learning (80%) better than online. The reason for being less understandable with online learning and the decreasing score of students, becomes the evaluation of online learning found in this research. That strongly becomes the reason why the students expect to have a better understanding of offline learning in 2022
